小鼠SRS-82细胞系和SAC-ⅡB_2、SAC一ⅡC_3克隆细胞株的染色体组型比较

A COMPARATIVE KARYOTYPE STUDY OF CELLS OF THE SRS-82 LINE,SAC IIB2 AND SAC-IIC3 CLONES IN MICE

本文研究结果表明,SRS-82细胞系的干系细胞染色体数是43,SAC-IIB_2细胞株的染色体数为多倍体,分布在75～91之间,SAC-IIC_3的干系细胞染色体数是41。三种细胞中均可看到A、B和M三种标记染色体,三种细胞的G显带核型也有差异。

Experimental results showed that the chromosome counts of the SRS-82 and SAC-IIC3 stem line cells were 43 and 41 respectively, where as the SAC-IIB2 stem line cells were polyploid. The chromosome markers A, B and M were found in all three kinds of colls. The karyotype differences by G-binding were also observed.
